everytime i launch the code and set the correct path it gives me this error, I tried including ffmpeg path, uninstalling and installing the library back but no luck. I’ve also tried using diffrent ways to set the path like putting it directly without saving it to a variable, this is getting me crazy please help me with a solution .
Code
from pytube import * import ffmpeg global str userurl = (input("Enter a youtube video URL : ")) q = str(input("Which quality you want ? 360p,480p,720p,1080p,4K,Flh :")).lower() yt = YouTube(userurl) print ("Title of the video : ",yt.title) def hd1080p(): print("Downloading a HD 1080p video...") v = yt.streams.filter(mime_type="video/mp4", res="1080p", adaptive = True).first().download(filename = "HD1080P.mp4") print("Video downloaded") yt.streams.filter(mime_type="audio") a = yt.streams.get_audio_only() print("Downloading audio") a.download(filename = "audio.mp4") print("audio downloaded") input_video = ffmpeg.input("HD1080P.mp4") added_audio = ffmpeg.input("audio.mp4").audio.filter('adelay', "1500|1500") merged_audio = ffmpeg.filter([input_video.audio, added_audio], 'amix') ( ffmpeg .concat(input_video, merged_audio, v=1, a=1) .output("mix_delayed_audio.mp4") .run(overwrite_output=True) ) if q == "1080" or q == "1080p": hd1080p() elif q == "720" or q == "720p": hd720p() elif q == "480" or q == "480p": l480p() elif q == "360" or q == "360p": l360p() elif q == "4" or q == "4k": hd4k() else: print("invalid choice")
THE ERROR

Answer
The simplest solution in Windows OS, is placing ffmpeg.exe
in the same folder as the Python script.
The reason you are getting the error, is that ffmpeg.exe
is not in the execution path of your operating system.
Note: Executing pip install ffmpeg-python
does not download FFmpeg application (but the Python package requires FFmpeg executable for functioning).
Assuming you are using Windows:
You can install FFmpeg
as descried here: How to Install FFmpeg on Windows.
My suggestion:
- Download the latest stable release from https://github.com/BtbN/FFmpeg-Builds/releases.
Static build in preferred (static build applies single executable file).
You may download a GPL licensed version (GPL versus LGPL is not relevant for executables).
The latest stable release up to date (Jan 23 2021) is 4.3.1
Assuming you are using Windows x64, download:ffmpeg-n4.3.1-29-g89daac5fe2-win64-gpl-4.3.zip
- Extract the ZIP file, and copy
ffmpeg.exe
to the same folder as your Python script. - In case it’s working, you may also put
ffmpeg.exe
someplace else (likeC:ffmpegbin
), and update the Windows path.
Update:
There is an option to execute ffmpeg.exe
, without adding it to the system path.
The method ffmpeg.run()
accepts the optional argument cmd
.
The default value of cmd
is ffmpeg
.
You can set the value of cmd
to the full execution path.
Example:
( ffmpeg .concat(input_video, merged_audio, v=1, a=1) .output("mix_delayed_audio.mp4") .run(overwrite_output=True, cmd=r'c:FFmpegbinffmpeg.exe') )
